Using assets of Adobe stock standard license

There are no fonts in Adobe stock. There are illustrations of letters, for which the same rules apply as other illustrations. Using them in a video would be a very slow process, better to get actual fonts.

Can I use illustrations of Adobe stock to create logos using standard license?

You can't create logos using Adobe stock.

Can I add  fonts of Adobe stock as texts in video using premier pro? 

By @amany28498126umdr

Yes. But I would use https://fonts.adobe.com. Those fonts are not part of Adobe stock. You have graphics in Adobe stock that represent characters, but they are not fonts in the sense of a computer font.

Yes. Audio comes with a standard licence. Video comes with an enhanced licence.

(Disclaimer: As always with licensing, this is my interpretation of the rules. I think they are correct and advice is based on reading and interpreting the licence terms and on fair use for both the buyer and the artist/stock company, but I cannot rule out that my interpretation is wrong. I'm not an Adobe employee).
